Cylindrical Cable Marking Unit with Split Enclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching marking elements, such as test stickers or labels, to cylindrical items like electrical cables are prone to damage, deformation, and loss due to constant bending, which can lead to safety issues and health risks, especially in the medical field.
Innovation Solution
A marking unit with a recording body comprising two sub-bodies that enclose the cylindrical element, providing a large attachment area for the marking element, which is designed to be securely attached and protected from damage, featuring a continuous surface for better adhesion and interlocking form elements for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the marking element is folded around the cable and the ends are glued together, then the marking element can be attached to the cable, but the flag can tear off or get caught during use and handling, damaging the marking element
Solution Approach 1:
The receiving body is divided into two separate partial bodies that can be assembled around the cable. This segmentation allows the marking element to be securely enclosed between the partial bodies without requiring the flag ends to be glued together, preventing tearing and catching issues
Solution Approach 2:
The marking element is nested within the receiving body formed by the two partial bodies. The marking element is positioned between the partial bodies and secured in place, protecting it from external damage while maintaining its visibility and functionality
2Reliability
If the marking element is attached to the cable, then it provides test information, but constant bending of the cable causes the marking element to deform and detach
Solution Approach 1:
The receiving body is designed with a protective structure that cushions and absorbs the stress from cable bending before it can reach the marking element. The partial bodies form a rigid enclosure that prevents deformation of the marking element during cable movement
Solution Approach 2:
The marking element is transitioned from a flat flag shape to a three-dimensional enclosed structure within the receiving body. This dimensional change allows the marking element to be protected from bending stresses while still displaying test information through its surface
3Reliability
If the marking element is attached with adhesive, then it can be secured to the cable, but dirt accumulates on the edges of the adhesive surfaces, reducing value and posing health hazards
Solution Approach 1:
The adhesive attachment method is extracted and replaced by a mechanical enclosure system. The two partial bodies form a physical barrier that seals the marking element, preventing dirt accumulation on adhesive edges while maintaining secure attachment through the structural design of the receiving body
